That happened entering the winter map, a message kept popping up to eat something then I closed the browser window, then I re-entered and I was dead but not in hell.
So right now I am a zombie. XD
It looks like closing the browser window saved you from your trip to purgatory, but in turn left you in an endlessly unfulfilled quest for brains as a Glitch zombie. We've fixed this so in the future you'll be sent to purgatory when you log back in. Thanks, punk (the player)!
